Abstract
BACKGROUND Chemotherapy is a standard strategy for stage IV gastric cancer patients. However, some cases cannot undergo conversion surgery because of their frailty, even if the patients had response to chemotherapy. For these patients, local tumor progression is a problem. We report here the case of a patient whose residual gastric cancer was resected through endoscopic submucosal dissection (ESD) after concomitant chemotherapy for metastatic gastric cancer.
CASE SUMMARY An 85-year-old male complained of difficulty swallowing, and examination revealed gastric cancer with multiple liver metastases. Although he received concomitant chemotherapy, a residual tumor was observed in the primary lesion while the metastatic lesions disappeared completely. Conversion surgery was considered optional treatment; however, he could not undergo that because of advanced age and comorbidities. Thus, we performed ESD to treat the residual tumor. As a result, we resected the residual lesion completely. The patient has been alive for 29 mo since ESD, without recurrence.
CONCLUSION We achieved local control using ESD, and these findings may provide therapeutic improvements both in local control and patient survival outcomes.

Abstract
Abstract
Background
Elevated levels of serum tumor maker p53 antibody is expected as an indicator of early diagnosis and a parameter of recurrence in breast cancer. P53 mutation accounts for 20% to 35% in all breast cancer patients. Preoperative high level of anti-p53 antibody in breast cancer patients tend to associate with worse prognosis. This study investigated the prognostic value of preoperative serum p53 levels, and the significance as a biomarker to evaluate a recurrence after surgical resections in breast cancer.
Methods
Preoperative serum p53 concentration levels were measured in total of 259 breast cancer patients, who had undergone either a total mastectomy or a partial mastectomy, through 2010 to 2015 in our facility. Patients with elevated levels of p53 (29 patients) and normal levels of p53 (230 patients) were compared to analyze the association of a marker level with the prognosis and the indication to diagnose recurrence in breast cancer.
Results
Elevated serum level of p53 mutation was identified in 29 (11%) patients. The size of tumor, staging, and pathology did not associate with the level of p53. Patients with elevated serum level of p53 correlated to the high score of nuclear grade (NG2 and NG3) and the high percentage of Ki-67 (>14%), which leading to the worse prognosis. Triple negative breast cancer was the major molecular subtype in the group of high level of p53 comparing with the group of low level of p53. Survival analysis using the Kaplan-Meier method were performed to examine DFS and OS of high serum level of p53 patients. Patients with high level of p53 were significantly showed worse DFS than a normal p53 group. Serum level of p53 was also reflected to the recurrence and metastasis of postoperative breast cancer. There were three patients, who had local recurrences and metastasis, in the group of high levels of p53. Their serum levels of p53 were re-elevated as emerging the local recurrence and metastasis once they had gotten the normal serum levels of p53 after surgical resections. It showed that the increasing of the level of p53 was reflected to the recurrence and metastasis of tumors after surgical resections in breast cancer.
Conclusions
This study suggests that preoperative serum level of p53 can be an independent prognostic parameter and a monitoring biomarker for breast cancer.

Abstract
The prevalence of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) is increasing worldwide. Several effective drugs for these diseases are now in development and under clinical trials. It is important to reveal the mechanism of the development of NAFLD and NASH. We investigated the role of arrestin domain-containing protein 3 (ARRDC3), which is linked to obesity in men and regulates body mass, adiposity and energy expenditure, in the progression of NAFLD and NASH. We performed knockdown of endogenous ARRDC3 in human hepatocytes and examined the inflammasome-associated gene expression by real-time PCR-based array. We also examined the effect of conditioned medium from endogenous ARRDC3-knockdown-hepatocytes on the apoptosis of hepatic stellate cells. We observed that free acids enhanced the expression of ARRDC3 in hepatocytes. Knockdown of ARRDC3 could lead to the inhibition of inflammasome-associated gene expression in hepatocytes. We also observed that conditioned medium from endogenous ARRDC3-knockdown-hepatocytes enhances the apoptosis of hepatic stellate cells. ARRDC3 has a role in the progression of NAFLD and NASH and is one of the targets for the development of the effective treatment of NAFLD and NASH.

Abstract
A 37-year-old man developed abdominal pain and the frequency of severe abdominal pain steadily increased to once a month. He was therefore admitted to our hospital. Abdominal CT showed bowel obstruction. It revealed transient stenosis in the small intestine. There were no symptoms such as fever or weight loss, it seemed unlikely that the patient had inflammatory bowel disease. Considering the history of recurrent abdominal pain, Familial Mediterranean Fever (FMF) was considered. As a result, a genetic analysis revealed mutations in exons 3 and 8 of the MEFV gene. We herein report the first known case of FMF with transient small bowel stenosis in Japan.

Abstract
The introduction of a direct-acting antiviral (DAA) for patients with hepatitis C virus (HCV) infection, could lead to higher sustained virologic response (SVR) rates with fewer adverse events, and it could shorten the treatment duration relative to the interferon era. Although most recent clinical studies have demonstrated that the occurrence rates of hepatocellular carcinoma (HCC) are decreased by SVR with both interferon-based and interferon-free-regimens, there are several reports about the unexpected observation of high rates of early tumor occurrence and recurrence in patients with HCV-related HCC undergoing interferon-free therapy despite SVR. Several mechanisms of HCC occurrence and rapid immunological changes, including cytokines and chemokines during and after DAA treatment, have also been reported. We focused on the possibilities that HCC occurs or recurs during and after DAA treatment, based on the reported clinical and basic studies. Further studies and observations will be needed to determine the short-term and long-term effects on hepatocarcinogenesis caused by the eradication of HCV with DAAs. New serum biomarkers and a follow-up system for HCV-patients with SVR should be established.

Abstract
The number of patients with nonalcoholic fatty liver diseases (NAFLD) including nonalcoholic steatohepatitis (NASH), has been increasing. NASH causes cirrhosis and hepatocellular carcinoma (HCC) and is one of the most serious health problems in the world. The mechanism through which NASH progresses is still largely unknown. Activation of caspases, Bcl-2 family proteins, and c-Jun N-terminal kinase-induced hepatocyte apoptosis plays a role in the activation of NAFLD/NASH. Apoptotic hepatocytes stimulate immune cells and hepatic stellate cells toward the progression of fibrosis in the liver through the production of inflammasomes and cytokines. Abnormalities in glucose and lipid metabolism as well as microbiota accelerate these processes. The production of reactive oxygen species, oxidative stress, and endoplasmic reticulum stress is also involved. Cell death, including apoptosis, seems very important in the progression of NAFLD and NASH. Recently, inhibitors of apoptosis have been developed as drugs for the treatment of NASH and may prevent cirrhosis and HCC. Increased hepatocyte apoptosis may distinguish NASH from NAFLD, and the improvement of apoptosis could play a role in controlling the development of NASH. In this review, the association between apoptosis and NAFLD/NASH are discussed. This review could provide their knowledge, which plays a role in seeing the patients with NAFLD/NASH in daily clinical practice.

Abstract
It has been elucidated that hepatitis B virus (HBV) DNA is frequently integrated to some cancer related genes such as TERT or KMT2B in patients with chronic HBV infection. On the other hand, it has not yet become clear of the integration of HBV to the genome of patients with prior infection with HBV. To identify the integration sites of HBV, we performed next generation of target capture technology for hepatocellular carcinoma samples obtained from 73 HBc antibody positive patients but negative for HBs antigen nor hepatitis C antibody (HCV) (Group 1; prior infection), 78 HBs antigen positive patients (Group 2; positive control), and 33 patients without any antigens nor antibodies for HBV (Group 3; negative control). Among these patients, overall HBV integration in Group 2 (54 patients, 69.2%) was significantly frequent compared with that in Group 1 (12, 16.4%) (P < 0.001), and was not detected in any patients of Group 3. On the other hand, HBV integration occurred in the known driver genes; TERT in seven (9.5%) and 12 (15.3%) patients (P = 0.332), MLL4 in two (3.5%) and four (5.1%) patients (P = 682), and CCNE1 in 0 and one (1.2%) patient (P = 1.000) in Group 1 and 2, respectively. Notably, integration of any driver genes was not observed in 56 patients with prior infection with HBV who were positive for HCV infection.Taken together, despite the disappearance of HBV, the frequency of driver events by HBV integration in patients with prior HBV infection is similar to those with chronic HBV infection, and patients with prior HBV infection are still at the risk of hepatocellular carcinoma.

Abstract
A 70-year-old woman with hepatitis C cirrhosis underwent balloon-occluded retrograde transvenous obliteration for hepatic encephalopathy due to spleno-renal shunt. Because the shunt was thick, long, and winding, we used a coaxial and double interruption system, which enables the effective occlusion of the drainage route, and shape-memory coils, which are more physically stable than conventional metallic coils because they form three-dimensional loops. The patient was successfully treated with the combined usage of these devices, resulting in a normal serum ammonia level. Thereafter, the patient was treated with direct-acting antivirals, and a sustained virological response was achieved.

Abstract
The patient was a 72-year-old woman whose alkaline phosphatase levels had been elevated since she was 56 years old. Liver biopsies obtained when the patient was 64 and 66 years of age led to a suspicion of cholangitis caused by vasculitis. Furthermore, proteinase-3 anti-neutrophil cytoplasmic antibody positivity led to a suspicion of granulomatosis with polyangiitis, but subjective symptoms and disorders in other organs were absent, so this suspicion was not confirmed. Cholangitis caused by vasculitis rarely occurs without vasculitis in other organs. We herein report this case in which we obtained distinctive laparoscopic and imaging findings that raised suspicions of liver circulatory failure.

Abstract
Background Excess iron is associated with non-alcoholic steatohepatitis (NASH). Results mRNA expression of duodenal cytochrome b, divalent metal transporter 1, ferroportin 1, hepcidin, hephaestin and transferrin receptor 1 in liver were higher in high fat, high cholesterol-containing diet (HFCD) group than in normal diet (ND) group. mRNA levels of divalent metal transporter 1 and transferrin receptor 1, which stimulate iron absorption and excretion, were enhanced in small intestine. Epithelial mucosa of small intestine in HFCD group was characterized by plasma cell and eosinophil infiltration and increased vacuoles. Iron absorption was enhanced in this NASH model in the context of chronic inflammation of small intestinal epithelial cells, consequences of intestinal epithelial cell impairment caused by HFCD. Iron is transported to hepatocytes via portal blood, and abnormalities in iron absorption and excretion occur in small intestine from changes in iron transporter expression, which also occurs in NASH liver. Knockdown of hepcidin antimicrobial peptide led to enhanced heavy chain of ferritin expression in human hepatocytes, indicating association between hepcidin production and iron storage in hepatocytes. Conclusions Iron-related transporters in liver and lower/upper portions of small intestine play critical roles in NASH development. Methods Expression of iron metabolism-related genes in liver and small intestine was analyzed in stroke-prone spontaneously hypertensive rats (SHR-SP), which develop NASH. Five-week-old SHR-SP fed ND or HFCD were examined. mRNA and protein levels of iron metabolism-related genes in liver and small intestine from 12- and 19-week-old rats were evaluated by real-time RT-PCR and immunohistochemistry or Western blot.

Abstract
A 68-year-old man with a history of diabetes mellitus was admitted to our hospital with a diagnosis of acute pancreatitis. Abdominal computed tomography revealed a suspicious tumor in the body of the pancreas, along with a dilated main pancreatic duct and edema of the pancreatic tail. Endoscopic retrograde pancreatography was performed after treating the patient's pancreatitis. When a cannula tip was advanced beyond the stenosis, deep into the distal pancreatic duct, thick white pus was evacuated. A bacteriological examination of the aspirated pancreatic juice revealed Enterobacter cloacae, and a cytological examination revealed adenocarcinoma. The diagnosis was acute obstructive suppurative pancreatic ductitis associated with pancreatic carcinoma.

Abstract
BACKGROUND Acute decompensated heart failure (ADHF) is often accompanied by liver congestion through increased right atrial pressure (RAP). Liver stiffness (LS) assessed non-invasively using transient elastography is related to increased RAP and liver congestion in patients with general HF. We investigated the relationship of LS with clinical and echocardiographic variables and outcomes in patients with ADHF.Methods and Results:The subjects were 105 patients with ADHF admitted to hospital between October 2016 and June 2017. Patients were divided into 2 groups based on median LS at admission (low LS <8.8 kPa [n=52] vs. high LS ≥8.8 kPa [n=53]). Death from cardiovascular disease and readmission for HF were primary endpoints. Total bilirubin and γ-glutamyl transpeptidase levels, MELD-XI score, diameters of the inferior vena cava and right ventricle, and severity of tricuspid regurgitation were greater in the high LS group (all P<0.05). During a median (interquartile range) follow-up period of 153 (83-231) days, cardiac events occurred in 29 patients (54%) in the high LS group and in 13 (25%) in the low LS group (P=0.001). After adjusting for variables that influence organ congestion, a high LS ≥8.8 kPa was still significantly associated with cardiac events (all P<0.05). CONCLUSIONS Increased LS measured by transient elastography reflects RAP elevation, hepatic congestion, and hepatic dysfunction. LS upon admission may be a useful prognostic marker in patients with ADHF.

Abstract
BACKGROUND AND AIMS Curability is associated with resection width and depth in polypectomy. We evaluated the resection width and depth achieved with hot snare polypectomy (HSP) and cold snare polypectomy (CSP) for small colorectal polyps. METHODS In this single-center, prospective, randomized controlled study, patients with rectal or rectosigmoid polyps ≤10 mm in diameter were treated with HSP or CSP. Resection width was evaluated as mucosal defect size, measured immediately postprocedure and 1 day later. Resection depth was histologically evaluated using obtained specimens. RESULTS Fifty-two patients were enrolled. Mean lesion size was 5.6 mm with HSP (n = 27) and 5.8 mm with CSP (n = 25). Mean mucosal defect diameter immediately after HSP and CSP was 5.1 mm and 7.5 mm, respectively (P < .001). The diameter 1 day after the procedure increased by 29% (95% confidence interval [CI], 17%-41%) with HSP and decreased by 25% (95% CI, 18%-32%) with CSP (P < .001). Muscularis mucosa was obtained similarly with HSP and CSP (96% [95% CI, 82%-99%] vs 92% [95% CI, 75%-98%]; P = .603). Submucosal tissue was obtained significantly more frequently with HSP than with CSP (81% [95% CI, 63%-92%] vs 24% [95% CI, 11%-43%]; P < .001). CONCLUSIONS The resection width immediately after CSP was larger than that after HSP but was significantly smaller at day 1 after resection. Although the resection depth after CSP was more superficial, muscularis mucosa was obtained in most specimens. Thus, CSP has sufficient resection width and depth to enable complete polyp resection and potentially has a superior safety profile than HSP.

Abstract
Background Interferon-free treatment can achieve higher sustained virological response (SVR) rates, even in patients in whom hepatitis C virus (HCV) could not be eradicated in the interferon treatment era. Immune restoration in the liver is occasionally associated with HCV infection. We examined the safety and effects of interferon-free regimens on HCV patients with autoimmune liver diseases. Results All 7 HCV patients with autoimmune hepatitis (AIH) completed treatment and achieved SVR. Three patients took prednisolone (PSL) at baseline, and 3 did not take PSL during interferon-free treatment. In one HCV patient with AIH and cirrhosis, PSL were not administered at baseline, but she needed to take 40 mg/day PSL at week 8 for liver dysfunction. She also complained back pain and was diagnosed with vasospastic angina by coronary angiography at week 11. However, she completed interferon-free treatment. All 5 HCV patients with primary biliary cholangitis (PBC) completed treatment and achieved SVR. Three of these HCV patients with PBC were treated with UDCA during interferon-free treatment. Conclusions Interferon-free regimens could result in higher SVR rates in HCV patients with autoimmune liver diseases. As interferon-free treatment for HCV may have an effect on hepatic immunity and activity of the autoimmune liver diseases, careful attention should be paid to unexpected adverse events in their treatments. Methods Total 12 patients with HCV and autoimmune liver diseases [7 AIH and PBC], who were treated with interferon-free regimens, were retrospectively analyzed.

Abstract
AIM Renal venous hypertension is known to be associated with worsening of renal function in patients with decompensated heart failure. Intra-abdominal hypertension including cirrhotic ascites also leads to renal venous hypertension. We aimed to clarify the effect of renal venous hypertension on cirrhotic ascites. METHODS Two hepatologists measured the left renal vein diameter in 142 consecutive patients with refractory cirrhotic ascites using non-contrast computed tomography. The renal vein diameter was measured at the renal vein main trunk and upstream of the confluence of collateral veins. RESULTS The inter-observer agreements were high for the measurements of the left renal vein (r = 0.918, P < 0.001). The median overall survival for patients with renal vein diameter ≥11 mm was less than that for patients with renal vein diameter <11 mm (P < 0.001; 2.5 vs. 32.0 months). One-year survival rates were 15.3% versus 66.4%. Multivariate analysis revealed renal vein diameter ≥11 mm (hazard ratio, 2.94; P < 0.001; 95% confidence interval, 1.67-5.20) and a high Model for End-stage Liver Disease score combined with serum sodium level (MELD-Na) (hazard ratio, 3.39; P < 0.001; 95% confidence interval, 2.00-5.74) were significant independent predictors of mortality. CONCLUSIONS Renal vein dilation is a risk factor of mortality in patients with refractory cirrhotic ascites, independent of the MELD-Na score.

Abstract
Programmed cell death ligand 1 (PD-L1) and its receptor PD-1 are immune checkpoint molecules that attenuate the immune response. Blockade of PD-L1 enhances the immune response in a variety of tumours and thus serves as an effective anti-cancer treatment. However, the biological and prognostic roles of PD-L1/PD-1 signalling in oral squamous cell carcinoma (OSCC) remain to be elucidated. The purpose of this study was to examine the correlation of PD-L1/PD-1 signalling with the prognosis of OSCC patients to assess its potential therapeutic relevance. The expression of PD-L1 and of PD-1 was determined immunohistochemically in 97 patients with OSCC and the association of this expression with clinicopathological characteristics was examined. Increased expression of PD-L1 was found in 64.9% of OSCC cases and increased expression of PD-1 was found in 61.9%. Univariate and multivariate analysis revealed that increased expression of PD-L1 and PD-1 positively correlated with cervical lymph node metastasis. The expression of CD25, an activated T-cell marker, was negatively correlated with the labelling index of PD-L1 and PD-1. Moreover, the patient group with PD-L1-positive and PD-1-positive expression showed a more unfavourable prognosis than the group with PD-L1-negative and PD-1-negative expression. These data suggest that increased PD-L1 and PD-1 expression is predictive of nodal metastasis and a poor prognosis and is possibly involved in cancer progression via attenuating the immune response.

Abstract
BACKGROUND Interferon-free treatment results in higher sustained virologic response (SVR) rates, with no serious adverse events in hepatitis C virus (HCV)-infected patients. However, in some patients with treatment-failure in HCV NS5A inhibitor-including interferon-free regimens, the treatment-emergent HCV NS5A resistance-associated variants (RAVs), which are resistant to interferon-free retreatment including HCV NS5A inhibitors, are observed. In HCV-infected Japanese patients with daclatasvir and asunaprevir treatment failure, retreatment with sofosbuvir and ledipasvir could lead to only ∼70% SVR rates. CASE SUMMARY Three HCV genotype (GT)-1b-infected cirrhotic patients who discontinued the combination of daclatasvir and asunaprevir due to adverse drug reactions within 4 weeks; retreatment with sofosbuvir and ledipasvir combination could result in SVR in these patients without RAVs. One HCV GT-1b-infected cirrhotic patient who discontinued the combination of daclatasvir and asunaprevir due to viral breakthrough at week 10; retreatment with sofosbuvir and ledipasvir combination for this patient with the treatment-emergent HCV NS5A RAV-Y93H resulted in viral relapse at week 4 after the end of the treatment. CONCLUSION Retreatment with sofosbuvir and ledipasvir is effective for HCV GT-1b patients who discontinue the combination of daclatasvir and asunaprevir within 4 weeks. The treatment response should be related to the existence of treatment-emergent HCV NS5A RAVs, but may not be related to the short duration of treatment.

Abstract
Hepatic schwannoma is a very rare hepatic tumor, usually appearing as a hypervascular solid mass with or without various degrees of cystic changes; however, to the best of our knowledge, only the two cases of hepatic schwannoma showing a multi-cystic appearance have previously been reported. We report herein a benign hepatic schwannoma presenting as an unusually large multi-cystic mass. The gadoxetic acid disodium-enhanced magnetic resonance imaging features are described with the histopathologic correlation and briefly review the literature. The solid-like areas showing the early/progressive enhancement, reflecting remnants of the Antoni A/B portion, during the dynamic phases may be helpful imaging features for the differentiation of other multi-cystic hepatic lesions, but pathological evaluation remains essential for diagnosis.

Abstract
Hepatitis A virus (HAV) infection is one of the major causes of acute hepatitis and acute liver failure in developing and developed countries. Although effective vaccines for HAV infection are available, outbreaks of HAV infection still cause deaths, even in developed countries. One approach to control HAV infection is prevention through diet, which can inhibit HAV propagation and replication. Glucose-regulated protein 78 (GRP78) is a member of the heat shock protein 70 family of molecular chaperone required for endoplasmic reticulum stress and stress-induced autophagy. We previously showed that the elevation of GRP78 expression inhibits HAV replication. It has been reported that Japanese miso extracts, which was made from rice-koji, enhance GRP78 expression. In the present study, we used human hepatoma Huh7 cells and human hepatocyte PXB cells to examine the efficacy of Japanese miso extracts as antiviral agents against HAV. Japanese miso extracts enhanced GRP78 expression and inhibited HAV replication in human hepatocytes. Together, these results demonstrate that Japanese miso extracts may partly modulate GRP78 expression and additively or synergistically work as antivirals against HAV infection. Japanese miso extracts can be used as effective dietary supplements for severe hepatitis A.

Persistent Hepatic Inflammation Plays a Role in Hepatocellular Carcinoma After Sustained Virological Response in Patients with HCV Infection. Int J Med Sci 2018; 15:466-474.

Abstract
Objective: Hepatitis C virus (HCV) infection has long been treated with interferon therapy (IFN). Currently, more than 90% of IFN-treated patients show a sustained virological response (SVR) when also treated with ribavirin and/or a protease inhibitor. Histological inflammation and fibrosis improve in IFN-treated patients, which indicates HCV clearance. IFN also reduces the incidence of hepatocellular carcinoma (HCC). However, a small proportion of patients with SVR develop HCC. To investigate the causes of hepatic carcinogenesis after SVR, we compared the liver histological findings before IFN to those after the development of HCC. Patients and methods: In total, 602 patients infected with type C chronic hepatitis or with liver cirrhosis who received IFN therapy during the period from 1992 through 2015 were included in this study. We assessed 14 of the 287 patients who achieved an SVR. Results: HCC was diagnosed by computed tomography, angiography or liver biopsy. The longest time from the SVR until HCC detection was 16.5 years, and the mean was 7.2±4.6 years. Nine of the 14 patients underwent surgery and one radiofrequency ablation. The histological findings of 10 patients were available for comparison. The comparison of the histological findings before treatment with those after the HCC diagnosis revealed an amelioration of liver fibrosis and other inflammatory changes. All ten patients showed improvements in fibrosis and steatosis. However, we observed that mild inflammatory change persisted from 1.8 years to 16.5 years after the confirmation of SVR in all cases. Conclusion: We suspect that persistent histological inflammation is one of the factors contributing to hepatocarcinogenesis (i.e., HCC development) even after successful treatment.

Abstract
AIM Diabetes mellitus (DM) is a potential risk factor for hepatocarcinogenesis, especially in patients with hepatitis C virus (HCV) infection. We aimed to elucidate whether DM influences the surgical outcomes of patients with hepatocellular carcinoma (HCC). METHODS Our patients were routinely controlled to keep urinary glucose excretion to less than 3.0 g/day before surgery, and the serum glucose level under 200 mg/dL after surgery. The surgical outcomes and postoperative complications of 112 patients with HCV-related HCC with DM (DM group) were compared to those of 112 propensity-matched patients without DM (non-DM group). RESULTS After a median follow-up of 3.2 years (range, 0.2-11.3 years), the median overall (5.2 years; 95% confidence interval, 3.8-6.5 years) and recurrence-free survival (2.2 years; 1.7-2.9 years) in the DM group were not significantly different from those (6.3 years; 5.4-7.1 years, P = 0.337; and 2.2 years; 1.7-3.6 years, P = 0.613) in the non-DM group. The independent factors related to overall survival were the background liver (hazard ratio, 2.06; 95% confidence interval, 1.27-3.39, P = 0.014) and tumor differentiation grade (2.07; 1.14-4.05, P = 0.015). Thirty-two patients (28.5%) in the DM group and 32 patients (28.5%) in the non-DM group had morbidities after operation, with no significant difference between the groups (P = 1.000). Furthermore, postoperative control status of DM did not affect the prognostic outcome. CONCLUSION Diabetes mellitus does not affect the surgical outcomes of patients with HCV-related HCC, and it is not an unfavorable factor when selecting candidates for liver resection of HCC.
